Python Open Source Packages
Welcome to my repository of open source
In addition to contributing to several open source projects, I have
published a few packages of my own. Questions, comments, bug reports,
etc. may be reported to: dpopowich AT astro.umass.edu.
For more information about my python experience, please see my Python
Software Engineering resume: pdf.

WSGIServlets is a lightweight web application framework written in
python for python's WSGI
specification. See PEP
3333 for details about WSGI.
It's a small, elegant, object-oriented framework that does not get in
your way. The home page for the project is hosted
at Google Code.
The project includes
and a tutorial. A live tutorial can be
Mod_python Servlets (mpservlets)
This project is no longer maintained. If you are a user of mpservlets
I strongly encourage you to upgrade to WSGIServlets. The last version
of mpservlets remains available here for those "stuck" using
mod_python and for posterity. It is built on top of, and requires,
mod_python 3.x (which in turn requires apache 2.x). Homepage
is here. The latest version, 1.1.6 can be
After programming a few PyGTK
applications I discovered over and over the need for two widgets not
available in the PyGTK library: a text-entry widget that validates its
input based on a user-defined callback, and tool tips (bubble help) for
the TreeView widget. After writing my own (and seeing many others in
forums in want of the same features) I published these two widgets. A
quick Google search will show these have been incorporated in several
open source projects.
ValidatedEntry, a PyGTK extension providing a validated Entry widget
ValidatedEntry is a subclass of gtk.Entry, providing validation of
input based on programmable functions. If you need to validate input
before accepting it, this widget can help. Sample functions included
in the package provide validation for integers, floats, non-empty
strings, ISBN numbers, phone numbers, money and bounded values (e.g.,
integers in a range). A demo app is included in the package. The
latest version, 1.0.4, can be downloaded here
TreeViewTooltips, a PyGTK extension providing tool tip support for
TreeViewTooltips is a class which presents tool tips for cells,
columns and rows in a gtk.TreeView. You need to subclass
TreeViewTooltips and implement the get_tooltip() method which
takes as input the TreeView and the TreeViewColumn and path of the
current row. Based on whether or not column and path are checked
for specific values, get_tooltip() can return tool tips for a cell,
column, row or the whole view:
|Column Checked||Path Checked||Tool tip For...
get_tooltip() should return None if no tool tip should be
displayed. Otherwise the return value will be coerced to a string
(with the str() builtin) and stripped; if non-empty, the result
will be displayed as the tool tip. By default, the tool tip
pop-up window will be displayed centered and just below the
pointer and will remain shown until the pointer leaves the cell
(or column, or row, or view, depending on how get_tooltip() is
A demo app is included in the package. The latest version, 1.0.0, can
be downloaded here.
